The black have better heatsink.
As for o-rings, if they deattached on both sides it means the trace which was connected to o-ring is broken. You may look around the missed o-rings and find disconnected trace. In such cases I'm scratching the coating of the trace and trying to make the trace copper clean from coating closer to the pin but keep the coating at surrounding ground and another traces. When broken trace is scratched and is clear, I'm soldering a thinnest wire from a strand right over the trace and the pin. This way the trace become connected to it's pin even if o-ring is absent.
About the RAID. Here in the last log are these records:
Rigth after AHCI device enable the messages from "md", Multiply Devices, aka Linux Software RAID are present.
May be your drives formerly were a part of software RAID? The file system look mounted earlier than when you booted with one drive active.
It will be better to debug in future test to increase debug level. To do that, you need to add a kernel parameter loglevel=6 into the boot configuration file.
The file is in /linux-root/boot/extlinux directory, "extlinux.conf". You need to add loglevel=6 into the line with kerner parameters on the flash drive:
original (example)
modified (example, look at the end of line)
If I'm not mistaken, the debug log you will get will contain much more information (level 6 is INFO level) about what is happening during a boot.
